Forum: etree Subject: Chipmunk-style streams?

Sorry if this has been addressed, but I didn't find any related topic yet...

I've noticed that several of the shows streaming from the new embedded player are played back at double speed (e.g. Chipmunk style). Is this a problem with one of my plugins, or an issue with the lossy deriver?

Example:

We've had a couple of sporadic reports, but I don't know if it's on 100% of the new shows, or what. So if you could leave an error report on the specific show(s) you hear with problems (use the link in the lower left of the show's details page), that could help establish a pattern for later troubleshooting. Thanks for help with that!

EDIT: Looks like a pattern, reporting it as a possible general problem....

Here's some more information (on that particular show). I tried all four streaming options (VBR and 64k, flash and local streaming), and only the combination of 64k streaming on the flash player produced the chipmunk sounds. It sounded fine when I tried VBR with the flash player, and with both MP3 formats on my local player (which, with all due respect to Jonathan, works much better in general--but then I am running Linux).

Didn't check the oggs, but then I can only stream those with my local player. (Another complaint I have about the flash player.)

I'd like to determine how widespread this is. Have you found more than a couple examples?

I sorted the collection by date added, saw a selection of shows added/derived post-transition, and ones I tried all sound fast in the flash player, random ex:

Firefox 1.5+ on WinXP SP2, if that helps.

Bummer - sounds pretty widespread. Unfortunately it doesn't seem like there's a whole lot I can do. The MP3s themselves, as others have pointed out, are fine. As such, it appears to be a bug with the Flash player, which is a 3rd party product. If anyone knows of another good opensource XSPF Flash audio player, I'd be happy to give it a shot.

Looking through the bug reports for the XSPF Web Music Player (which appears to be the one you're using), the general concensus seems to be that the problem is in Flash itself, not in the player. If this is true, then finding another player is unlikely to help. On the other hand, if finding another player does help, then someone should notify the musicplayer folks that they actually do have a bug.

Curiously, the most recent report (and the only one that's still open) suggests that the problem only occurs if the bitrate is NOT a multiple of 16, while the Archive is only seeing the problem with files whose bitrate IS a multiple of 16.

I looked (or tried to look) at the player that PhunkyZen pointed to, but it requires Flash8, and I only have Flash7. I suspect that could be a problem for a lot of people, since this is the first I'd heard that there even was a Flash8. And if the problem is in Flash (and not the player), it's possible that upgrading to Flash8 would fix the problem in any case. Someone who cares enough to try upgrading their flash might want to investigate.

also of note:

the 'pause' feature seems to have time limit before it changes the position to the 'stopped' position. I.E. if you pause a show in the embedded streaming player. you can 'un pause it' in the near future, but if you leave it paused for ~ 5 minutes or so, (maybe less) the player will go to the 'stop' position and if you hit 'play' thinking it will resume at the original paused position, it will not. it will start at the beggining of the song (since it was 'stopped').

Actually, the %16Khz (ok with multiples of 16Khz) may not be quite right. Other reports say that Flash only plays MP3s correctly if encoded in the following Khz rates:
11Khz, 22Khz, 44Khz

Although other INTARWEB references also say that things are fine if you use a multiple of 16KHz or only for 64/96/128Khz. Or is that Kbps? Ah! See the compatability table here - there is a difference:

http://loudblog.de/forum/viewtopic.php?id=46 has a compatability table which lists working bitrates.

Or, Google for "chipmunk mp3 flash"

http://music.podshow.com/music/faq.htm claims that 8 khz, 11.025 khz, 12 khz, 16 khz, 22.05 khz, 24 khz work.

Macromedia Flash's "Publish" settings apparently have a fixed number of bitrates. I guess this would give us a good clue as to what might work and what might not. Why MM opted to hardcode these is probably best known to them, I'm sure there's a good reason :)

You may want to ask Macromedia to fix this:

... but if it's fixed in Flash8 (first I'd heard too - wow, once upon a time a new Flash vers was all the news) then I wouldn't bother :)

Two huge (insurmountable) problems with this theory: first, the Archive's VBR MP3s play fine, and second of all, only some of the Archive's 64k MP3s have chipmunk problems.

don't really have a theory, xtifr, but perhaps you have?

above is just pointing to other references, nothing to debunk here, move along.

hyperlink points but not is

i got mine working fine anyway ... good luck, dude!

only some of the Archive's 64k MP3s have chipmunk problems

But specifically, the some = every one created since the changeover, none prior to the changeover.

i have the same problem with a show i uploaded. i am calling it the streaming chipmunk syndrome:
http://www.archive.org/details/Seven_League_Boots_Mar31_06.mp3

so this is not fixable?

I found this player that does support xspf/rss playlists:

http://www.jeroenwijering.com/?item=Flash_MP3_Player

It seems that the license is ok for this site since it's non-commercial.

Jon,

FYI, I tried loading one of the LMA-generated xml playlists into the player from www.jeroenwijering.com, and it suffers from the same problem with 64k files. I also upgraded to the latest version of Flash 8, and that didn't help either.

This is an issue with Flash in general... or perhaps the two players derive from the same codebase and suffer from the same flaw. :)
